The diagrams will show how the figures are constructed--each with the
seven Tangrams. It will be noticed that in both cases the head, hat, and
arm are precisely alike, and the width at the base of the body the
same. But this body contains four pieces in the first case, and in the
second design only three. The first is larger than the second by exactly
that narrow strip indicated by the dotted line between A and B. This
strip is therefore exactly equal in area to the piece forming the foot
in the other design, though when thus distributed along the side of the
body the increased dimension is not easily apparent to the eye.
